SHAREHOLDER ALERT: Brower Piven Encourages Investors With More Than
$150,000 in Losses from Investment in OSI Systems, Inc. to Contact
Brower Piven Before the February 10, 2014 Lead Plaintiff Deadline

January 31, 2014 09:00 PM Eastern Standard Time

STEVENSON, Md.--(BUSINESS WIRE)--Brower Piven, A Professional Corporation announces that a class action
lawsuit has been commenced in the United States District Court for the
Central District of California on behalf of purchasers of OSI Systems,
Inc. (“OSI Systems” or the “Company”) (NasdaqGS: OSIS) securities during
the period between January 24, 2012 and December 6, 2013, inclusive (the
“Class Period”).

If you have suffered a net loss from investment in OSI Systems, Inc.
securities purchased on or after January 24, 2012, and held through any
of the revelations of negative information on November 14, 2012, January
22, 2013, and/or December 6, 2013, as described below, at no cost to
you, you may obtain additional information about this lawsuit and your
ability to become a lead plaintiff by contacting Brower Piven at www.browerpiven.com,
by email at hoffman@browerpiven.com,
by calling 410/415-6616, or at Brower Piven, A Professional Corporation,
1925 Old Valley Road, Stevenson, Maryland 21153. Attorneys at Brower
Piven have combined experience litigating securities and class action
cases of over 60 years.

No class has yet been certified in the above action. Members of the
Class will be represented by the lead plaintiff and counsel chosen by
the lead plaintiff. If you wish to choose counsel to represent you and
the Class, you must apply to be appointed lead plaintiff no later than
February 10, 2014 and be selected by the Court. The lead plaintiff will
direct the litigation and participate in important decisions including
whether to accept a settlement and how much of a settlement to accept
for the Class in the action. The lead plaintiff will be selected from
among applicants claiming the largest loss from investment in the
Company during the Class Period.

The complaint accuses the defendants of violations of the Securities
Exchange Act of 1934 by virtue of the defendants’ failure to disclose
during the Class Period that the Company manipulated operational tests
of its Advanced Imaging Technology by selectively picking the best
sensors, and that the Company’s products raised strong privacy concerns
and were manufactured with parts that directly violated contracts with
the Transportation Security Administration (“TSA”), thereby risking
cancellation of the contracts. According to the complaint, following
November 14, 2012 news reports that a key congressman disclosed that the
Company may have committed fraud by “knowingly manipulating” the results
of an operational test in connection with the Company’s Advanced Imaging
Technology, the January 22, 2013 disclosure that the TSA had ended its
contract with the Company and that OSI Systems would have to bear the
costs of removing all Rapiscan full body scanners from airports, and the
December 6, 2013 disclosure that the TSA had canceled a $60 million
contract for the company’s carry-on baggage screening equipment, with
the possibility of a future ban on contracting with the Department of
Homeland Security, the value of OSI Systems shares declined
significantly.

If you choose to retain counsel, you may retain Brower Piven without
financial obligation or cost to you, or you may retain other counsel of
your choice. You need take no action at this time to be a member of the
class.
